Question

2. Define the following:-
(a) Atmosphere
(b) Humidity
(c) Glacier
(d) Denudation
(e) Wind
​

Answer 1

Here it is:)

Explanation:

Atmosphere: An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body

Humidity: Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye.

Glacier: A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.

Denudation: denudation involves the processes that cause the wearing away of the Earth's surface by moving water, by ice, by wind, and by waves, leading to a reduction in elevation and in relief of landforms and of landscapes.

Wind: Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air

Answer 2

Answer:

a)The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earth and forming its planetary atmosphere.

b) Humidity is the amount of water vapor in the air. ... Relative humidity is the amount of water vapor actually in the air, expressed as a percentage of the maximum amount of water vapor the air can hold at the same temperature.

c)A glacier is a huge mass of ice that moves slowly over land. The term “glacier” comes from the French word glace (glah-SAY), which means ice. Glaciers are often called “rivers of ice.” Glaciers fall into two groups: alpine glaciers and ice sheets. Alpine glaciers form on mountainsides and move downward through valleys.

d)In geology, denudation involves the processes that cause the wearing away of the Earth's surface by moving water, by ice, by wind, and by waves, leading to a reduction in elevation and in relief of landforms and of landscapes.

e) wind is a natural movement of air of any velocity especially : the earth's air or the gas surrounding a planet in natural motion horizontally.
